You also can specify a constraint when adding a package, like so:
```bash
poetry add pendulum@^2.0.5
poetry add "pendulum>=2.0.5"
```
If you try to add a package that is already present, you will get an error.
However, if you specify a constraint, like above, the dependency will be updated
by using the specified constraint. If you want to get the latest version of an already
present dependency you can use the special `latest` constraint:
```bash
poetry add pendulum@latest
```
You can also add `git` dependencies: You can also add `git` dependencies:
```bash ```bash
poetry add pendulum --git https://github.com/sdispater/pendulum.git poetry add git+https://github.com/sdispater/pendulum.git
```
If you need to checkout a specific branch, tag or revision,
you can specify it when using `add`:
```bash
poetry add git+https://github.com/sdispater/pendulum.git@develop
poetry add git+https://github.com/sdispater/pendulum.git@2.0.5
